DEVICE AND METHOD FOR EFFICIENTLY PERFORMING IFFT FOR ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) MODULATION

A communications device includes at least one memory device (102) for storing complex exponential functions as approximations of sine and cosine basis waveforms. A logic circuit (108) adds and subtracts the complex exponential functions to generate an Orthogonal Frequency Division Multiplexed (OFDM)...
